The analysis and design of a zero voltage switching (ZVS) full bridge DC/DC converter control is discussed in this paper. The power converter is used to regulate the output dc voltage. With this objective, the control strategy presented here is designed based in the equations that describe the output current and output voltage dynamics. The proposed controller employs a dual-loop scheme implemented...
Modulation of multilevel converters is the focus of researchers looking for high quality of the output waveforms with low losses. This paper shows that multiple switching sequences can be used in order to generate the desired phase voltage. A simple two-dimensional modulation technique for two-cell multilevel cascaded converters is introduced in this paper. Using a two-dimensional control region,...
The use of an inverter with an output LC filter allows for generation of output sinusoidal voltages with low harmonic distortion, suitable for uninterruptible power supply systems. However, the controller design becomes more difficult. This paper presents a new and simple control scheme using predictive control for a two-level converter. The controller uses the model of the system to predict, on each...
